Hi,
the good news first. The modem works under linux in both modes (cdc_ether and
mbim).
cdc-ether-mode works well in dualstack too without special treatment.
I have some problem with dualstack in mbim-mode.
Using just the Networkmanager it only uses ipv4. If I use the ModemMananger
manually with dhclient(and slaac) afterwards, I get dualstack working.
But the ModemManager doesn't know about it:
mmcli -b 3

On the other hand, when using an older mbim-modem (K5150) it works. I tested
with master of libmbim and master modemmanager.
Any ideas where I should continue to search?
Special settings with mbimcli?
Regards,
Thomas
